I am interested in having a product called Durastone installed in my kitchen but the company that is going to install it said I would have to have the 3 layers of vinal flooring removed. I know that the 3rd layer was installed in 1990 but the other 2 layers are most likely 1980'ish or before. Do you have any advise for this matter. Do you think I should try and remove them or should I find someone to do it for me. The kitchen is about 12 x 15 in size. I would appreciate any advise that you have for me.
